This is an app that creates a workaround for a problem with some character encoding in the pdfToolbox Place Content fixup when used in Switch on Mac. The encoding problem affects non-ASCII characters such as some Scandinavian and German characters. Note that the problem don't exist on Windows.
It will use callas pdfToolbox to process, you set up a kfpx-profile with the Place content fixup and use it in this app.
You have a multi-line property field for the variables that are sent to pdfToolbox in the same manner as the pdfToolbox configurator.
